Answer:
B)attach specifically to host cell receptors
Explanation:
Viral spikes are one of the envelope proteins. These proteins are coded for by viral genes. Viral spikes project from the envelope surface. They are also called peplomers. One of the functions of these spikes is to specifically interact with the receptors present on the surface of the host cell to mediate the attachment of the virus to the host cell surface. Viral spikes and the host cell surface receptors are complementary to allow their specific binding. For example, the spike protein of the SARS-coronavirus bind specifically to the human host cell receptor ACE2.

Answer:
In biology, the relationship in which one organism lives inside another is described by the term endosymbiosis.
Explanation:
Endosymbiosis refers to a form of association that organisms have, in which one individual lives and performs his functions within another's body -using his resources to survive- being called the first symbiont, and the second host.
An example of endosymbiosis is found in bacteria that are part of the intestine of some living organisms, contributing to the process of food degradation.
Additionally, endosymbiosis is relevant in explaining the origin of eukaryotic cells from symbiosis between prokaryotic cells, which is known as endosymbiotic theory.

Answer:
the answer is D
Explanation:
Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.
